1 Claim.

This invention relates to an automatic lighting means for gas orgasoline stoves.

It is aimed to provide a novel construction wherein the gas will beignited automatically upon opening the supply valve and a constructionwherein the same system may be utilized for operating a number ofburners, so that a single source of electrical energy will suffice.

The more specific objects and advantages will become apparent from aconsideration of the de-- scription following taken in connection withaccompanying drawing illustrating an operative embodiment.

In said drawing:-

Figure 1 is a View showing my improved system or mechanism in connectionwith a gas burner;

Figure 2 is a detail section taken substantially on the line 22 ofFigure 1 and on an enlarged scale;

Figure 3 is a detail section taken on the line 33 of Figure 2, and

Figure 4 is a detail section taken on the line 3-4 of Figure 1.

Referring specifically to the drawing wherein like reference charactersdesignate like or similar parts, Ill designates a conventional burner asis used on a gas stove or gasoline stove and I! is the supply conduitthrough which the fuel is passed thereto. An elongated rod [2 has avalve 13, seated in the pipe H and held by fastening means at 14, thevalve having an orifice i5 therethrough through which the fuel passeswhen the valve is open, that is in a position at 90 to that shown inFigure 1.

Rod i2 is rotatable and has a sleeve ll slidable thereon and adapted formanipulation by means of a handle Ill. The sleeve ll has an elongatedslot [9 therein through which a screw 20 passes to fasten it againstaccidental displacement from the rod l2. Sleeve l'l abuts a slide 2|which surrounds the rod 12 forming a journal bearing therefor, and isurged outwardly by an expansive coil spring 22 surrounding rod l2,abutting the fuel pipe I l at one end and the slide 2| at the other end.Slide 21 is square and slidably and non-rotatably mounted in a squareopening of a guide or bracket 16a connected to the stove.

The gas or fuel issuing from the orifices 23 of the burner is adapted tobe ignited by an electric spark produced from a plug means at 24. Suchplug means may comprise an angular metallic support 25 extending fromthe burner and carrying a grounded electrode 26 co-acting with anelectrode 21 carried by a porcelain or other insulating body 28, thecontact or electrode 21 preferably being fastened to the insulation bymeans of nuts 29 and 30 and being removably and adjustably fastened inplace by means of a cleat 3i disposed over the body 28 and fastened tothe support 25 by means of screws 32, it being realized that the support25 and cleat 3| are notched or cut away to conform to the shape of thebody 28. By reason of this construction, the spark plug may be readilyremoved and the electrodes may be removed, adjusted or replaced.

The electric energy for operating the plug may be supplied from anysuitable source, for instance the house lighting current or a storagebattery, the latter being suggested at 33. A conductor 34 leads from oneterminal thereof to a conventional spark coil 35 having breaker points36. Said conductor 3:; has spaced apart contacts 31 therein. A groundwire 38 leads from the other terminal of the battery and is grounded tothe burner or other metallic parts, for instance the support 25. Anotherconductor 39 leads from the secondary of the coil 35 to a contact 40.

Slide 2! has a lateral arm 4| from which a post 42 of insulation risesand which post carries a switch conductor 43 and an upper conductor 44,respectively engageable with the contacts 3? and Ail.

When the device is operated from the off position shown in the drawing,handle 18 is turned 90 so as to place the valve orifice or port it: in

the battery to the coil and spark plug, since the 7 contacts 53 and 37engage and the contacts 4! and i l engage, and a conductor 45 leads fromthe latter to the electrode 21. The electrode 26 is preferably removablyheld in place by a screw 46 threaded to the support 25. As a result ofthe closing of the circuit, a continuous spark is produced at the sparkplug so long as the circuit remains closed. It will be realized, thatthe circuit will open as soon as the handle i3 is released because ofthe expansive action of spring 22. With the present type of switch andcircuit, having the breaker points, as many burners as desired may beconnected in the circuit and operated from the one coil and from thesame source of electric energy.

Various changes may be resorted to provided they fall within the spiritand scope of the invention,

I claim as my invention:-

A device of the class described comprising a valve rod, a slidesurrounding and forming a journal bearing for said rod and locatedintermediate the ends of the latter, said slide being polygonal in crosssection, guide means having an opening occupied by the slide andcorresponding to its polygonal shape, an operating sleeve engaging oneside of the slide, said sleeve being slidably mounted on the rod, a pinand slot connection between the sleeve and rod whereby operation of thesleeve will turn the rod relatively to said slide, a spring surroundingthe rod at the opposite side of the slide to the sleeve also engageablewith a support, and contact means controlled by the slide.
